Highpass / Bandpass Filter mod

Highpass / Bandpass Filter mod

2011-11-22 by Jeppe Madsen

Hi. Do you know if there is a Highpass / Bandpass filter mod for the MP4? Or is it possible to mod the Mono/Poly and install an extra filter stage (like with the MS20)?

Thank's
Jeppe

I don't know any solution to implement a highpass with an SSM2044
(beside known halfhearted workarounds like mix the filtersignal with the
phase inverted original signal).

An additional Filter shouldn't be a problem. The bigger problem might be
the required additional Potentiometers.

perhaps it is a good idea to add an insert between VCF and VCA, so you
could add an external filter.

Yes that would be nice. Maybe before the LPF. Then I could use the trig out to trigger an external envelope and filter?
